Affymetrix GMS417

The Affymetrix GMS417 (formerly Genetic Microsystems) arrayer is based on the pin-and ring technique. This technique involves dipping a small ring into the sample well and removing it to capture liquid in the ring. A solid pin is then pushed through the sample in the ring and sample trapped on the flat end of the pin is deposited onto the surface. This apparatus allows us to customize arrays for individual investigators and address specific biological questions. This arrayer is particularly useful with alternative spotting chemistries (e.g. Surmodics 3D link technology for printing oligonucleotides, or attaching DNA and protein covalently to glass). This arrayer is best suited to fabricating low density arrays.
